Application fi ea July 31, line. Serial No. 782,234.

To all whom it may concern:

vat'ion of the slide, Fig. 0

same, and Fig. 6 1s a cross sectional v1ew of Be it known that I, PATRIQK J. Connors, a. -c1t1zen of the United States of America,

residing at Greenville, in the county of Mercer and State-of Pennsylvania, have invented certain new and useful Improvements in Safety Devices for ater-Gages, of which the following is a specification,

"reference being had therein to the accompanying drawing.

This is an improvement in connection with a safety device for water gages disclosed in my pending application filed February 10, 1913, Serial Number 74:7,410. Besides having the same objects in view as disclosed in my pending application, the

'present invention aims to provide the slide of the protecting device with an outlet or drain opening, whereby broken glass, steam or other matter that may accumulate within I attain the above and other objects by mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure l is a rear elevation of a safety device provided with my improvement, both of which are partly broken away, Fig. 2 is a rear elevation of the detached slide embodying the improvement, Fig. 3 is a side elevation of the same. Fig. 4 is a front eleis. a plan of the the slide.

In order that those not conversant with my pending application may understand to a certain degree the application of the present improvement, there is illustrated in Fig. 1 a rear elevation a casing 1 having connections2 for a glass tube adapted to re- 'ceive hot water and discharge steam or hot Water at the upper end thereof. The casing has walls provided with transparent plates and. the rear wall has a dovetailed tapering seat 3 for a shutter or slide l. The shutter or slide is dovetailed and tapered to lit in the seat 3 and the upper end of said slide has an outwardly extending handle or lip 5 whereby it can be easily moved into and out of engagement with the seat 3 of the casing 1. The slide 4, intermediate the ends thereof, is pr vided with an oblong opening 6 that is in communication with a sleeve coupling member or elbow 7, said member being formed integral with the rear or other side of the slide. The lower end of the member or elbow T isinteriorly screw threaded, as at 8 to accommodate a pipe (not shown) should it be necessary to utilize such a conduit in connection with the safety device. j

As disclosed in my pending application,

the safety device has been designed to prevent firemen, engineers and others from be ing injured by flying glass or steam when the water gage bursts. The casing 1 constitutes a transparent inclosure and. prevents flying glass or steam from injuring persons in proximity to the gage. To prevent the flying glass or steam from injurii g the casing or subjecting it to undue stresses or strains, the slide l thereof, which has been used to permit of the casing 1 being easily cleaned, has the outlet or discharge opening 6. This opening not only relieves the pressure withinthe casing, but provides an outlet or discharge for. flying glass, steam, hot water and in reality the contents of the casing when the gage bursts. In some instances it may not be necessary to use a pipe in connection with the member 7, as said member serves as a deflector for all matter dischar ed by the opening 6, the matter being delfected downwardly whereby it can do little, if any, harm.

It is thought that my-improvement will be apparent in view of the disclosure of my pending application, and as in connection with this pending application it is to be understood that the structural elements are susceptible to such changes as fall within the scope of the appended claim.

What I claim is The combination with a safety device for Water gages embodying, a'casing having one of the Wallsthereof provided with a dove tailed seat, of a dovetailed tapering slide detachably inountedin the seat of said' cas- 'ing and having the upper end thereof provided with a handle, said. slide having an opening formed therein, and a member carried by 831d slide and 1n commumcatlon .with said opening and having proyision'for a condult connectlon.
